Bug Description

When "11n_disable=1" is passed to iwlagn module the issue does not occur, at the cost of losing wireless-n connectivity.
Wireless connectivity recovers but any sessions are lost ie ssh -Y opened applications.

This was never really a linux-firmware package bug. It likely should have been filed against linux, but I also think this particular issue is much better . Please try 12.04 or the 12.10 Beta.
